An analytical study of the role of selected metal ions in bone and joint diseases
Published 1995“…The speciation of the titanium (III)/titanium (IV) complexes in the biological matrices was investigated with Fourier transform infra red (FTIR) spectroscopy and high field proton nuclear magnetic resonance (NMR) with a Hahn spin echo pulse sequence. The chemical nature of non-protein bound iron present in knee joint synovial fluid obtained from RA patients was also investigated by use of NMR…”

Novel opto-electronic and plastic fibre sensors
Published 1998“…The middle POF is coupled to a red LED and emits light onto a flat target with the two outer fibres receiving the reflected light from the target and guiding it to two silicon PIN photodiodes. Theoretical investigations on the behaviour of the sensor are presented for ranges between 0 mm and 100 mm, and for targets with different reflectivities. …”
